SPECIFICATION forming part of Letters Patent No. 714,950, dated December 2, 1902.

Application filed May 7, 1901l Serial No. 591100. (No model.)

To tu whom t may concern:

Beit knownthat 1, FRANCIS H. RICHARDS, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Bearings, of which the following is a specification.

This invention relates to a bearing, and relates more particularly to such a device which is adjustable and which is adapted for use in machines where precision in assembling the parts is desired.

In the accompanying drawings, Figure 1 is a central vertical section through a support and a member supported thereon connected by one form of my device, parts being shown in elevation. Fig. 2 is a front elevation of these parts. Fig. 3 is a side elevation of the connecting member with a part in section. Fig. 4 is a front end elevation thereof, and Fig. 5 is a side elevation of the binding-screw.

Similar characters designate like parts throughout the several figures of the draw'- ings.

Some suitable support designated by the numeral 10 is preferably provided with a bearing-face at 11, which lnay be conveniently formed upon the end of a boss 12. Through this boss, preferably at or near its center and extending, if desired, into the body of the support, is a socket or opening 13, which may be provided with a screw-thread 14. From the inner wall of the opening 13, with its axis preferably coinciding with the axis thereof, is a depression or recess l5, havinga thread 16.

The numeral 17 designates a crank-arm or like member which it may be desired to support upon the part 10. This is shown as having a boss 18 upon its inner side, the end of which is trued off to form a face for coaction with the face upon the support. Through the member 17 and its boss is an opening 19, having a preferably conically-tapered and inwardly-converging surface 2O at its outer end and an enlarged portion 21 at its inner end. The opening 19 is adapted to receive a bearing-stud or connecting member 22, having a tapered portion 23 fitting the tapered surface 2O of the opening to enable the crankarm to rotate thereon, and a cylindrical threaded portion 24,which engages the thread 14 and permits the connecting member to be adjusted toward or from the support to bring and maintain the tapered surfaces and the coacting faces into the desired contact to allow rotation of the supported member and at the same time to fix its axis in position relatively to the support. A slot 25 in the outer end of the member 22 enables it to be readily turned by the application of a screw-driver, andthe enlargement 21 of the opening 19 permits some movement of the tapered portion 23 inward in its adjustment to take up wear.

To fiX the connecting member in position, it is shown as provided with an axial cylindrical opening 26 in alinement with the threaded opening 13 and at the outer end of this opening with an enlarged recess 27. Through the opening 26 may extend a binding-screw 28, in this instance shown as atension-screw, having its thread 28L engaging the thread 16 on the support, its smooth cylindrical portion 2S fitting the opening, and its head 2Sc at the outer end of the bearingstud seated in a recess 27. When the stud is adjusted to the proper position, the binding-screw may be turned in until the pressure of its head in the recess will force the inner face of the thread upon the stud against the coacting face of the thread 14s and clamp the stud firmly in place. The bearingsur face of the binding-screw thereon will be so much less than that between the thread of the stud and the support that it will not disturb the adjustment.

This arrangement of bearing presents many advantages in use. The opening through the bearing-stud may be drilled and reamed or ground, so that it is truly cylindrical, and the tapered and threaded portions turned up true with the opening, securing a more accurate positioning of the supported member than could be otherwise attained. This feature, together with the maintaining of the fixed relative position, which is obtained by the coacting bearing-faces and the tapered surfaces, makes this device particularly effective in machines of the precision class. The location of the head of the binding-screw at the outside of the support on the same side and n ico proximity to the end of the supporting-stud renders the parts easy of access and convenient to assemble and adjust.

Having thus described my invention, I claiml. The combination with a support having a socket of a su pported member provided with a tapered opening; a connecting member provided with a longitudinal opening and having a portion engaging with the Walls of the Socket in said support and a tapered portion coacting With the tapered opening in the supported member; and a binding screw extending through the longitudinal opening in the connecting member and engaging with said support.

2. The combination with a support having a threaded socket of a supported member provided With a tapered opening; a connecting member provided with a longitudinal opening and havinga portion engaging with the thread of the socket in said support and a tapered portion coacting with the tapered opening in the supported member; and a binding-screw extending through the longitudinal opening in the connecting memberand engaging With said support..

3. The combination with a support having athreaded socket and atthe base of the socket a threaded depression, of a supported member provided with a tapered opening; a connecting member provided With a longitudinal opening and having a portion engaging the thread of the socket in said support and a tapered portion coacting with the tapered openingin the supported member; and a binding-screw extending through the longitudinal openingin the connecting member and engaging with the threaded depression at the base of the socket in the support.

4. The combination with a support having a socket and a bearing-face, of a supported member provided with a coacting bearingface and a tapered opening; a connecting member provided With a longitudinal opening and having a portion engaging the Walls of the socket in said support, and a taperedA portion coacting with the tapered opening in the supported member; and a binding-screw extending through the longitudinal opening in the connecting member and engaging With said Support.

5. The combination with a support having a socket, of a supported member provided with a tapered opening; a connecting member provided with a longitudinal opening and having a portion engaging the Walls of the socket and a tapered portion coacting with the tapered opening in the supported member; and a binding-screw extending through the longitudinal opening in the connecting member and engaging With said supported member and having its head contacting with the outer end of the connecting member.

6. The combination, with a support and a member to be supported provided With an opening tapered at its outer portion and enlarged at its inner portion, of a connecting member provided with a longitudinal opening and having a portion engaging the support and a tapered portion coacting with the tapered opening, and a binding-screw extending through the longitudinal opening and engaging the support.

7. The combination with a support having a cylindrical socket of a Supported member provided with a tapered opening; a connecting member provided with a longitudinal opening and having a cylindrical portion secured in the socket in said support and a tapered portion coacting with thetapered opening in the supported member; and a bindingscrew extending through the longitudinal opening in the connecting member and engaging with said support.

8. The combination with a support having a cylindrical socket and a bearing-face, of a supported member provided. with a coacting bearing-face and a'tapered opening; a connecting member provided with a longitudinal opening and having a cylindrical portion secured in the socket in said support and a tapered portion coacting with the tapered opening in the supported member; and a bindingscrew extending through the longitudinal opening in the connecting member and engaging with said support` 9. The combination with a support having a threaded cylindrical socket and at the base thereof a threaded depression, said support also having a bearing-face, of a supported member provided with a coacting bearingface and a tapered opening; a connecting member provided with a longitudinal opening and having a threaded cylindrical portion secured in the threaded socket in said support and a tapered portion coacting with the tapered opening in the supported member; and a binding-screw extending through the longitudinal opening in the connecting member and engaging with the threaded depression at the base of the socket in said support.
